provements in Snow Bisposal, of which the following isla epeoication,reference being had therein to the accompanying drawing.y

My invention relates to the disposal of snow in streets b y temporarilystoring it on a part of the area where' it falls andsubsequently'removing it, either before or after the snow-fall i lt is dthat the snow blockade of 1919492() cost the city of New York some sixtymillions of dollars, no available means of removal proving adequate andslush, freezing in conduits andinalring the ruiming of cars impossibleeven after all surface ice had been laborioi'lsly removed, daysafter thestorm ceased.

l select those portions of the sidewalks and .iavements which are mostindispensable to tralilc. and move the snow laterally from those parts'to portions not so essential.. allowing no great accumulation of snowon the portions to be kept fairly clear-'for use, removing snow from thestorage areas as soon or as rapidly available facilities will permit. Bythis means, the pavement and sidewalk are virtually narrowed, but areotherwise readily kept in condition for use, snow never being thrownback and forthto and from the car tracks, for example, as'most townshaving only ordinary methods meet the situation, allowing the streetcleaning force and the street railway management to fight the matter outin thus repeatedly handling the same snow.

In the accompanying drawings, which are diagrammatic,

Fig. l is a cross-section of a street with my invention in use. ,A

Fig. 2 is a. similar section, snow being indicated. y

` Fig. 3 is an analogous-section showing a slight modification.

Fig. l is a section showing a different form of snow-retaining Stringer.

Fig. 5 is a like section showing parallel stringers tied together 'andarranged for at will increasing their height.

Fig. 6 is a perspective view of a tie bar used in vincreasingy theheightr of the stringers.

F l7 is a similar View of a tie bar used for detachably connecting thestringere at the street surface. f Fig.l 8 is a sectional view showing asimple Stringer connected to the curb byfaflat tie lying on thesidewalk. f

represents fthe surface In these figures, A of a street provided withstreet railway tracks B, B,.one of the sidewalks normally extendingfrom* the usual curb D Vto the building line E. Stringers Fare laid,parallel to the curbs, along all the lstreets in the area to which theinvention is to be applied, so that every street will have on each side.a strip laterally bounded by these stringers, and snow falling on otherportions of the street and sidewalk is piled upon this strip, so thatwith a moderate force of men any great accumulation of snow on thesidewalk or street may be prevented, the stored snow beine` removed byother men meantime, or byltthe same men afterthe snow ceases to fal Thestringers employed may be of wood such as scantling, or may bedownwardly open V-shaped structures of metal or wood, as shown at F,Fig. 3, or may be metal L bars F2, shown in Fig. 4.

The second form shown has the advantage of allowing melted snow or rainto flow down inclined street surfaces and ultimately pass into thesewers. One of these stringere may, if desired, be placed in each gutteras shown in Fig. 2 to prevent accumulation of" water when conditions aresuch that snow melts rapidly, thus avoiding the necessity of shovelingthe snow to forman open channel in the gutter.

In some cases, I lay down metal bars G, shown in Fig. 7', to receivestringers F", Fig. 5, and should the accumulation of snow continue solong as to make it desirable, these stringers can be increased in heightby placing upon their upper edges metal tiebars I having upwardly anddownwardly turned retaining projections I, I to en'- gage both the lowerstringer and the additional superposed Stringer J. Of course thisextension in height may be repeated, each added set of stringers .beingtied by a; set of crossbars.

In Fig. 8 a single Stringer F4 is shown as held parallel to and at asuitable distance from, the curb D by a thin, Hat bar G bent up ato'neend and down at the other and secured to the Stringer and, ifdesired, to the curb by a screw or the like.

It is also plain that I am not limited to ya single Stringer nor to asingle pair of Yzo stringers, nor to one stringer on the sidewalk andone on the street roadway, and it is equally clear that the length ofthe tie `bars may be varied according to the condil ing gutters andcurbs, the combination with a readily removable snoweretaining stringerparallel to and everywhere at a selected distance from the curbs, ofthin bars resting on the same surface as the Stringer and holding thelatter in place upon said surface.

2.- The method of disposing of snow falling in a city street whichconsists in providing readily removable snow retaining devices boundinga relatively narrow. area eX- tendingv lonigtudinally with reference tothe street, removing to such varea snow falling alongside the same, andat a later time mechanlcally removing the snowA from that area.

3, For temporarily storing snow `falling in city streets, thecombination with stringers laterally bounding the less used strips ofthe street area, of ties detachably connecting the stringere, and meansfor at will r increasing the vertical height of the stringers.
